When the system pipeline is used, the system pipeline is influenced by the pressure of flammable and explosive media such as coal gas and the like in the pipeline, so that the position of the welded junction is easy to leak, namely, a leakage point exists on the welded junction. Limited by the characteristics of the medium in the pipeline, and ignition construction cannot be carried out. Therefore, the existing leakage stopping mode aiming at the position of the weld crater generally adopts the hoop to compress the sealing gasket at the leakage point position of the weld crater, because the weld crater is in an irregular shape, and the weld crater is higher than the pipeline, the hoop is used for compressing the flexible sealing gasket at the position of the weld crater leakage point, the tight fitting of the sealing gasket and the position of the weld crater leakage point cannot be realized, namely, the online leakage stopping of the pipeline weld crater cannot be realized by the existing mode, so that an enterprise can only stop to stop leakage stopping, and the normal production of the enterprise in the process can cause great influence and is high in cost.
